Internally connected triple connection structure of curtain wall keel

Abstract

The invention discloses an internally connected triple connection structure of a curtain wall keel, which comprises a vertical keel and two horizontal keels connected to both sides of the vertical keel through a connecting component. The groove, the connecting component includes a sliding member that can pass through the through mounting hole and move along the laterally inwardly expanded groove. The sliding member is installed through the through mounting hole and can rotate relative to the through mounting hole. The connecting parts are respectively located in the laterally inwardly expanding grooves of the two horizontal keels and only slidingly fit with the laterally inwardly expanding grooves, and the vertical keels and the sliding parts are fixedly connected through the first fastening component. The invention has the advantages of simple and convenient disassembly and assembly, high connection strength, high stability and reliability, low cost, and is conducive to improving the appearance of the curtain wall, such as simplicity and delicacy.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an inline triple connection structure of a curtain wall keel. Background technique [0002] At present, the connection of horizontal and vertical keels in the market is mainly splicing and welding. Among them, there are two types of splicing: one is the sequential installation method in units, that is, the first vertical keel is installed first, and then the horizontal keel and the vertical keel are alternately installed on the side of the first vertical keel until the entire curtain wall is completed. The other is the post-installation method of the horizontal keel, that is, install all the vertical keels of the curtain wall according to the set interval size, and then install the horizontal keels between the adjacent vertical keels. The disadvantage of the above-mentioned former installation method is that once errors or other factors need to replace the keel ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing curtain wall technology for post-installation of transverse keel is not mature enough, and there are many defects as follows:

[0004] 1. It is difficult to hide the connectors and screws between the keels, and most of the connectors and screws are exposed, which not only affects the installation of the curtain wall panels, but also makes the appearance of the curtain wall after installation not simple and delicate;

[0005] 2. The number of connectors and screws required for the connection between the keels is large, resulting in difficulty in disassembly and assembly and low efficiency, and it is also necessary to open a large number of fastening installation holes on the keel, which will affect the strength of the keel and reduce it. Rust resistance of the keel

[0006] 3. The force transmission between the keel and the connector is directly fastened by screws. There are problems such as difficulty in guaranteeing the connection strength, easy loosening and failure, and low safety. Moreover, the screws are all connected to the side wall of the keel, and the force balance is stable. And poor stability, the side wall of the tubular keel is also easily deformed and damaged, which requires high wall thickness of the keel, increasing the weight of the keel and the overall cost
